Cancer Patient and Internet Star Zach Sobiech Passes Away [VIDEO]

We first introduced you to Zach Sobiech in 2012 when a video of him singing his original song 'Clouds' went viral. It became even more famous when learning that Zach was a cancer patient and had written the song as a "goodbye" to his loved ones. And just last week we brought you a video of the biggest stars in all of entertainment honoring Zach with a cover of the song. Well, this time the update is more heartbreaking than heart warming.

Zach Sobiech passed away Monday morning after a long battle with cancer. The 18 year old passed away peacefully at his home surrounded by his family and long time girlfriend. Zach had been fighting osteosarcoma, an extremely rare form of bone cancer, since he was 14. Last summer his doctors gave him months to a year to live. Instead of mourning and spending his last days grieving, he became a worldwide inspiration.

“It is with heavy heart that we announce the passing of our son Zachary David Sobiech,’’ the family said in a statement. “Our family has been blessed not only by his amazing presence in our lives, but also by the love and support of our family and friends and by so many people in the community. In particular we'd like to thank those people who listened with their hearts and helped Zach bring his message and his music to the world.”

Before passing, Zach got to celebrate his 18th birthday and attend his senior prom. His song became an anthem for children everywhere battling cancer. Actor Rainn Wilson took special interest in Zach, even making him the subject of a documentary. In the documentary, Zach made his last words something that we should all live by.

"I want everyone to know you don't have to find out you're dying to start living."
